Message Signaled Interrupts (MSI) Question


Recommended Posts

Is it true that MSI mode is not really needed if the IRQ for the device is NOT shared by another device (Meaning the device has its own dedicated IRQ)? If this is true then it explains why my video card has MSI mode turned off when it has its own IRQ and turned on when it is sharing the IRQ with other devices.

I don't need to jump to conclusions and to be polite, you would be referring to sarcasm would you?

I'm trying to prove a point with these A**'s over in the Creative Reddit forum. They really pray to the Message Signaled Interrupts as if it is the god that fixes all latencies and audio dropouts (Which is not the case). What is causing the issues they so dearly complain about is UEFI firmware that is poorly written. Actually it is the fault of 3: Microsoft, Driver makers and UEFI firmware makers.

Funny, cause Microsoft already fixed it.  https://docs.microsoft.com/en-us/windows-hardware/drivers/audio/low-latency-audio

 

Obviously they can't control the other two issues, or the software people use that uses ancient audio paths.

Hello,

 

Creative Labs' SoundBlaster cards were somewhat persnickety on ISA and PCI buses, so I don't necessarily know if I would blame current problems on PCIe bus engineering issues.  That said, there are not a lot of players left in the discrete sound card space (ASUS and EVGA come to mind), so options are limited if you want to do/use something beyond the capabilities of most on-board audio subsystems.  My primary desktop system is an EVGA Z370 Classified K which features "Creative's Sound Core 3D Audio" that I believe is the same as the Recon 3Di and hasn't worked for the last couple of versions of Windows due to its drivers not being updated to fix architectural issues that cropped up.  So, I am definitely sympathetic to anyone trying to troubleshoot issues with Creative Labs sound cards.

 

One of the things I noticed being given as a kind of universal panacea over in the subreddit was the installation of some kind of modded driver pack.  I don't know if that is the case that it will help, but it definitely does say something if their customers have to rely on homebrewed device driver support because the company can't be bothered to update its Windows drivers.

 

Regards,

I actually have the following:

*Asus Maximus XI extreme motherboard (Z390)

*with the Sound Blaster AE-9 pcie sound card.

*Intel Core i9 9900k

*32Gb RAM.

*Samsung 970 Pro NVMe 1Tb

_______

I've come to the conclusion that it's A UEFI Firmware issue that can be fixed through an update, but creative needs to work closely with the motherboard makers to fix the audio dropout issue.

It’s over his head so he is belittling instead of helping.

    • Can you get a brand new (not refurb) device like this, but with 2025 hardware, for $266? Under $300? No? If you can, it must have the worst specs otherwise (4gb ram, 1366x768 12in lcd screen, 256gb spinning hard drive, etc.). Please show me this sub-$300 2025 laptop that is better than what the article shows.

    • Honestly, i either don't care, mind, use, or had any problem with those. 11 is really good for me, has a lot of little refinements, looks great, if i wanted to tweak/fix it's behavior i would with a range of tools, and wouldn't come back to the 2010's looking Win 10 even at gunpoint.
